To all whom 'itmay concem:

Be it known that I, FREDERICK Gnonop of lVellington, in the Province of Ontario, Canada, have invented certain new and use ful Iuproveinents in Disk Harrows, of which the followingl is the 'specifica-tion.

My invention relates to improvements in disk harrows andk the object of theinvention is to devise a frame joining uprights or con nections eplaced' on parallel lines at right angleswith theline of draft, the said uprights or connections beingplaced at suitable locations on these parallel lines, and in which the independent pairs of gangsse cured thereto willjbe staggered lin relation to each other when in an inoperative posi tion and wherein the pair on each side-of the frame will come into allnenient when in an operative position. The gangs do better work and are lessliable to become clogged in this form.

A further ob]ect 1s to -devlse means for l swinging the gangs into an inoperative position wherein-the disks are parallel to the line of draft, or into anpperat'ive posit-ion wherein the disks are at an angle tothe line of draft.

A still further object is to devise a connection between the gang and the frame' which will permit of the gang moving ver tically relatively to the franre soas not to cut too .deep when traversing luinps or uneven ground.

The invention consists of a staggered frame joining uprights or connections placed on parallel lines at right angles with the line of draft, the said uprights orconnections having suitable tongues -at the bottone thereof formed at' the outer endsl of the stag ably connected to the' said uprights, and

levers for swinging the gangs of disks into an operative. or inoperative position all as hereinafter more particularly described andl illustrated in the aecompanyingdrawings in. whichzy 1 Figure 1, represents a perspectiveview of the device constructed according to my inv vention.

Fig. 2, is a plan l.view thereof. Fig. 3, isa perspective detail of the frame.

Fig. el, isa detail showing the method of connecting the gangs of `disksto-tlie upright. Fig. 5, is a perspective view ot' the sleeves gangs of disks. HUNT, of the town, of Elora, in the countyl connecting the levers on the traine with the Like letters of reference indicate eorrefy 4spending parts`in each figure.

1 the rear portion of tlie frame and 2 are the staggered portions with downwardly and inwardly inclined ends 3 havingtongues k4 formed at. the bottom thereof.

5 are inwardly inclining uprights secured to the rear portion 1 of the frame and having tongues et formed at the bottoms thereof. y v- G and 7 are the outer gangs having disks, and 9 and 10 are the gangs wit-hdisks 8.

ll are sleeves u ounted on the axles 12 of the respective gangs andbetween collars 1l secured to the axles. In the present instance the gangs' are each composed of seven disks 8 comiected to each axle l2. The sleeves ll are preferably niountedin this case between l the' third and fourth disk freni the outer end in each gangl 13 are sockets formed on the front of the sleeves '1l and designed to have the tongue 4 ot the uprights 3 and 5 inserted therein, the tongues being of substantially greater depth than the depthof the sockets.

1st are cotter pins inserted in apertures 15 in the tongues et to prevent the latter from slipping out of the sockets.

1 (3 are sockets formed on the rlear of the sleeves .lit and designed tohave yuprights i7 insertedl therein which hold the scraper bars 18 and the Scrapers 19 in `place.

20 is a. longitudinal beam rigidly Secured 'to and extending from the portion l of the trarne to ,a cross bar 2l which extendsbetween the poles 22. idly secured at. their rear ends to the porltions-Z of the Trame( gered portions of the frame, similar up- .rights suitably connected to the rear bar ofy the frame, independent gangs of disks suit- H23 Vare bracesA extending from the rear por tion' ot the traine l to the bearn Q0.

. Q4 are 'sleeves mounted on the axles 12 of the gangs between collars 24' and having the sockets 25 frmed on the front` of the said These poles 22 are rigf" ifo the gangs will swing into an operative position with the disks at an anglito the line of draft, both right and left hand pairs of gangs incliniiig inward, and by moving the levers backward the gangs will swing into an inoperative position with the disks parallel to thevline of draft (as shown by the dotted linesin Fig. 2), the two rear gangs 9 and 10 being. in `the same line and the two vfront gangs G and 7 being in the same line but staggered in relation to the rear gangs. Further the tongues Agbeing considerably longer than the depth of the sockets 13 the gangs will be allowed acertain amount of vertical play, and in this manner the cnt made by the disks will be even when going over depressions or lumps in the ground. If

for instance the gang 9 runs over a lump or y invention without departing from the spirit of the. same or the scope of the claims and the form shown is to be taken in an illustrative and not in a limiting'sense. `For instance although the harrow shown in the drawing is outthrowing, by reversing the frame an intlirowing harrow canV be-constructed quite as eticiently Further I do not wish to confine myself to the form of frame shown as any frame joining uprights or connections placed on parallel lines at right angles to the line of draft may be used with efficiency.

l/Vnat I claim as my invention is- 1. A disk .barrow comprising a frame having end portions in alinement with each other and an offset central portion paralleling said end portions, depending 'portions 9. A disk harrow comprising a frame having end portions in alinement with each other and an oitset central portion paralleling said end porticns,`a plurality of pairs of gangs connected to said frame and means for independently swinging the gangs of each pair in to operative and inoperative position. v 4.

3;`A disk liarrow comprising a frame having end portions in alinement with each other `and an offset central portion paralleling said end portions, a plurality of pairs` of gangs connected to said frame, and 4ineans for simultaneously swinging one gang of ea ch pair -intb alinement with the next adj acent gang and at an angle to the line of draft. y

4.. A disk harrow comprising a frame having end portions in alinement with each otlier and an offset central portion paralleling said end port-ions, said end' portions having 4integral downwardly and inwardly inclined members, inwardly inclined uprights connected to the extremities of said oiset sol central portion, a gang pivoted to each of I said integral inclined members and said iiiclinedy uprights, and means for simultaneously swinging one of said gangs into operative position and into alinement with the v next adjacent gang.
